YARN-SEPARA'FOR FOR SPINNING-FRAMES.

SPECIFICATION forming part of Letters Patent No. 553,102, dated January 14, 1896.

Application filed April 18, 1893. Seria1llo.4'70,819. (N0 model.)

.To aZZ whom it may concern:

Be it known that I, Gnonon IE. CHANDLER, a citizen of the United States, residing at Fall River, in the county of Bristol and Commonwealth of Massachusetts, have invented a certain new and useful Improvement in Yarn- Separators for Spinning-Frames, of which the following is a specification.

My invention relates to yarn-separators for spinning-frames and it consists in the devices and combinations hereinafter described and claimed, the principal objects of said invention being to lessen the cost of the separating devices, to enable them to be applied readily to any spinning-frames without alteration of said frame, and said invention including means of partly counterbalancing the weight of the separators and separatorbar, means of regulating the upper and lower limits of the traverse of the separators, and means for moving the separators out from between the bobbins for the purpose of doffing.

In the accompanying drawings, Figure l is a front elevation. of parts of a ring-spinning frame,showin g the roller-beam, thread-board, finger-board,1-in g-rail, spindlerail, guide-rail, a lifting-rod, the crossshaft and its arms and weight, a part of the chain which actuates said rock-shaft in one direction and a part of the rod which connects the upper arms of the different cross-shafts, showing also spindles, bobbins, cops, showing also the separator-bar, separators, and one of the separater-l iftin g brackets attached to said liftin grod; Fig. 2, a vertical section on the line 2 2 in Fig. 1, showing also a side elevation of a part of the frame, the counterbalancingweights and their pulley; Fig. 3, a side elevation of one of the adjustable separatorsupporting brackets and a vertical cross-section of a separator-bar, showing in side elevation a separator attached thereto, in the position it occupies in dofiing; Fig. a, a front elevation of the parts shown in Fig. 3; Fig. 5, a side elevation, and Fig. 6 a front elevation, of the separator-lifting bracket; Fig. 7, a front elevation of a part of a spindle-rail, part of a ring-rail and lifting-rod, part of a separator-bar, separators secured thereto, a separator-liftingbracket and a separator-sup- ,w porting bracket.

" The frame A, roller-beam l3, thread-board.

Ginger-board C, yarn-guides C spindle-rail D, spindles (1, supported on said rail, bobbins d, on which the yarn is wound in the form of cops (Z the ring-rail E, spinning-rin gs supported on said ring-rail, the lifting-rod e", guided vertically in the spindle-rail D and guide-rail F and with other such rods (only one being shown) supporting the ring-rail E, the cross-shaft G, supported in brackets f, secured to the guide-rails at opposite sides of the machine, said cross-shaft having arms, one, g, of which is connected to the buildingchain I:[ to rock said cross-shaft arm in one direction, another, g, of said arms carrying a weight g to rock said cross shaft in the other direction, and the third, of said cross-shaft arms reaching under the lifting-rod e to raise the ring-rail when the cross-shaft arm is rocked by the descent of its weighted arm g. These parts are all of the usual construction and operation and form no part of my invention.

The separator l is a thin blade 1' of sheet metal having a shank 'i secured to a horizontal separator-bar J by means of a screw 6 substantially as shown in United States Patent No. 476,731, granted June 7, 1.892, to Alfred 1). Chandler. The separators I may be the same in form as those described in said patent, or of the form shown in the drawings, the shape of said separators not forming any part of my invention, but being the invention of said AlfredD. Chandler. In the patent re ferred to the separator-barJ is represented as being raised by the direct action of the same cross-shaft arm on vertical rods (therein called separator-rods) similar to the lifting-rods E which support the ring-rail,tl1ese separatorrods having adjustable feet and adjustable collars which, with said separatora'ods, the separator-bar, the sockets which connect said separator-bar and separatonrods and the separators secured to said separator-bar, as shown in said patent, impose an extra duty upon the cross-shaft during a portion of the iraverse of the ring-rail and have some tendency to cause an uneven traverse of said ring-rail at the time when said separator-rods and the parts supported thereby begin to traverse. I dispense with these separator-rods and raise the separator-bar J and attached separators I by means of lifting-brackets N, the same beingprovided with sleeves a, each having a sliding fit on a lifting-rod e and adjustably supported on said. lifting-rod by a set-screw n which turns in said sleeve it against said lifting-rod. Each bracket N, of which there are as many as there are lifting-rods, is curved upward and backward, as shown in Figs. 2 and 5, from a horizontal to a vertical position, and is provided in its upper end above the ring r-ail E with a vertical slot n of a suitable size to receive the separator-bar J when the latter is in position for use and said lifting-bracket rises high enough to raise said separator-bar oil the supporting-bracket P, (hereinafter described,) on which said separator-bar rests during the operation of dotting and during the first part of the upward movement of the ring-rail.

Evidently the limit of the upward movement of the separator-bar and separators may be varied by varying the distance of the collar n from the under side of the ring-rail. The supporting-bracket P is formed in two parts 1) 1), one of which is provided with a vertical slot 13 through which bolts 12 are driven into the other of said parts, said slot 19 being long enough to allow, when the nuts p on said bolt-s p are loosened, a considerable vertical adjustment of the upper part, 13, on the lower part, 19, to vary the lower limit of the traverse of said separators. The lower part of the bracket P is rigidly secured by bolts 2) to the spindle-rail D.

To the top of the part 19 of the braoketP is pivoted, at 13 a fork p or slotted piece which normally stands vertically, as shown in Fig. 2, the slot 19 in said fork being of a suitable size to receive said separator-bar J and to allow the same to be raised out of said slot p by the above-described action of the liftingbracket N. The top of the upper part of the bracket P is provided with a vertical. front stopp which prevents the fork p from falling forward from the vertical position, with a back stop 7), which prevents the separatorbar from being removed from said fork when the separators l are in the position for doif- 'ing, (shown in Fig. 3,) and with a horizontal stop 19 or table on which said fork rests when said separators are in their vertical or dofiing position. The back stop 19 is also curved forward, as shown in Figs. 2 and 3, concentrically with the pivot of the fork p far enough to prevent the separator-bar from being removed from said fork, except when the separators are in their horizontal or working position.

The separator-bar is held in position for doffing by the friction thereon of a leaf-sprin g 19 secured to said back stop, as shown in Figs. 2 and The separator-bar is prevented from any longitudinal movement, and the proper lateral intervals between the separators I and the bobbins cl are maintained by pins j,which project from the front or the rear face or from both the front and the rear faces of said separator-bar and enter and loosely fit notches p in the top of the fork p and by other similar pins j, which enter and loosely fit similar notches n in the top of the lifting-bracket X. one set of the pins j or j being at all times in engagement with their appropriate notches p or n.

The weight of the separator-bar J and separators I is so small and so nearly counterbalanced by the weights Q, connected by a cord q, chains or other flexible connections passing over pulleys q journaled on the rollerbeam B, that very little power is required to raise them, the excess of the weight of said barJ an d separators I over that of the weights Qbeing just sufficient to cause said bar J and separators to move with thelifting-bracket X in its descent until said bar is stopped by the fork p I claim as my invention-- 1.
